Zelenskyy says Ukrainian flag flies in Lyman again, as Russia pulls troops from city

After being encircled by Ukrainian forces, Russia pulled troops out Saturday from an eastern Ukrainian city that it had been using as a front-line hub. It was the latest victory for the Ukrainian counteroffensive that has humiliated and angered the Kremlin.

Russia's withdrawal from Lyman complicates its internationally vilified declaration, just a day earlier, that it had annexed four regions of Ukraine — an area that includes Lyman.

Taking the city paves the way for Ukrainian troops to potentially push further into land that Moscow now illegally claims as its own.

"The Ukrainian flag is already in Lyman, Donetsk region. Fighting is still going on there. But there is no trace of any pseudo-referendum there," Ukrainian President Volodymyr Zelenskyy said in his nightly address Saturday.

He was referring to "referendums" that Russia held at gunpoint in the four regions before annexing them — Luhansk, Donetsk, Zaporizhzhia and Kherson.

The fighting comes at a pivotal moment in Russian President Vladimir Putin's war. Facing Ukrainian gains on the battlefield — which he frames as a U.S.-orchestrated effort to destroy Russia — Putin this week heightened threats of nuclear force and used his most aggressive, anti-Western rhetoric to date.

Russia's Defence Ministry claimed to have inflicted damage on Ukrainian forces in battling to hold Lyman, but said outnumbered Russian troops were withdrawn to more favourable positions. Kyiv's air force said it moved into Lyman, and Zelenskyy's chief of staff posted photos of a Ukrainian flag being hoisted on the town's outskirts.

Lyman had been an important link in the Russian front line for both ground communications and logistics. Located 160 kilometres southeast of Kharkiv, Ukraine's second-largest city, it is in the Donetsk region near the border with Luhansk region, two area Russia annexed Friday.

Ukrainian forces have retaken vast swaths of territory in a counteroffensive that started in September. They have pushed Russian forces out of the Kharkiv area and moved east across the Oskil River.

Moscow's withdrawal from Lyman prompted immediate criticism from some Russian officials.

The leader of Chechnya, Ramzan Kadyrov, blamed the retreat, without evidence, on one general being "covered up for by higher-up leaders in the general staff." He called for "more drastic measures."

Meanwhile, on the Russian-annexed Crimean Peninsula, the governor of the city of Sevastopol announced an emergency situation at an airfield there. Explosions and huge billows of smoke could be seen by beachgoers in the Russian-held resort. Authorities said a plane rolled off the runway at the Belbek airfield, and ammunition on board caught fire.

Russia annexed the Black Sea peninsula of Crimea from Ukraine in 2014 in violation of international law.

Russian bombardments have intensified in recent days as Moscow moved swiftly with its latest annexation and ordered a mass mobilization at home to bolster its forces. The Russian call-up has proven unpopular at home, prompting tens of thousands of Russian men to flee the country.
